Oh, C2O is linear in shape as well.
I thought you meant CO2

Deadly King, since you are so awesome, do you know what is the shape of C2O? they asked us to draw it (giving us info- like it should be C-C-O, and no unpaired electrons, and one of the atom is surrounded by only 6 electrons)

Do you have any more details about the question ???
Did it suggest that it is a dimer?
Because oxygen usually has two lone pairs of electrons. If it donates both of them and as well as forming two normal covalent bonds, it will have eight bonded electrons.
No unpaired electrons in the whole molecule or only on carbon or oxygen?

I don't think so. :-[
cs:
The question is about about free radical.. definition, and why NH2 as free radical, its C2O, and not CO2. i don't really get the question, i wrote bent as my answer, :D

Ahaaaa......now it's clearer.
Compound C2O gotta be : C=C=O
The first carbon atom (left) has two bond pairs of electrons and one lone pair of electron. Hence in all it has 6 electrons around it.
This same carbon will be the radical. ;)
Am afraid the answer is not bent. :-[
Ari was right. It has to be linear.

I think i drew it correctly. i wrote bent cos there's lone pair(which i know- its wrong now), its okay.. but why is it linear, is it because as long as there's 2 bond pair, its linear? ignore the lone pairs? (trying to learn, paper 1 left).. :D
